SQA0.G38 Valve Series

GAS Cartridge - 420 bar
Direct acting with anti-cavitation - Poppet Type

More details

Description
Direct acting in-line sequence valve with steel housing.
The SQA combines in one easy-to-install in line valve the typical
function of shock relief and anticavitation through the check valve.
In the pressure relief function it provides very low pressure rise
thanks to the smart deflector design.
When the pressure at the high pressure inlet (1) reaches the valve
setting, the valve starts to open to tank (2).
In the free reverse flow function a very light bias spring allows for    
ease of flow passage from nose to side (2 to 1).
High precision machining guarantees quick response to load chang-
es, limited hysteresis and reduced leakage.

Technical Features
All external surfaces are zinc plated and corrosion-proof.
All valve parts are made of high strength steel.
Highly stressed parts are hardened and ground to guarantee mini-
mal wear and to extend service life.
Pressure setting is pre-adjusted by the factory and cannot be
changed.
Optional spring ranges to 420 bar (6000 psi).
Back pressure on the tank port (port 2) is directly additive to the
valve setting at a 1:1 ratio.
GAS ports.
